Fresh hacks every day
[Bruce Land], professor at Cornell, is a frequent submitter to our tip line. Usually he sends in a few links every semester from undergraduate electronics courses. Now the fall semester is finally over and it’s time to move on to the more ambitious master’s projects.
First up is a head-mounted eye tracker, [Anil Ram Viswanathan] and [Zelan Xiao] put … Read the rest
Regular Hackaday readers will be familiar with all the cool things you can do with FPGAs; emulating old video game consoles, cracking encryption protocols, and DIY logic analyzers become relatively simple projects with even a modest FPGA dev board on your workbench. Many FPGA boards aren’t geared towards prototyping, though, and breadboard friendly devices are hard to come by. Here’s … Read the rest
The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great example. [Michael] just finished building it using a Papilio board.
Of course we’re not talking about discreet chips here. The Papilio is an FPGA development board which … Read the rest
For this year’s 7400 logic competition, [Nick] decided to build an FPGA out of logic chips.
Perhaps a short explanation is in order to fully appreciate [Nick]‘s work. The basic component of an FPGA is a slice, or cell, that performs boolean operations on its input and sends the result on its output. The core of these slices is … Read the rest
If you’re just starting out in your quest to build really cool electronic devices, you’ll find a ton of options ready for the beginner. The Arduino makes toggling pins dead simple, and the Raspi brings the wonders of blinking a LED from the command line down from the gods and into the hands of the common man. These are all … Read the rest
We love to see derivative works that take a great hack and make it even better. This LCD Laptop resurrection project is an excellent example. [Alex] took the work seen on this other FPGA LCD driver and delivered a leap forward on the final hardware packaging.
The link at the top drops you into the second page of [Alex's] project … Read the rest
The Mandelbrot set – the fractal ‘snowman turned on its side’ seen above – has graced the covers of magazines, journals, and has even been exhibited in art galleries. An impressive feat for what is nothing more than a mathematical function, and has become something of an obsession for [Chiaki Nakajima].
Even on modern computers, generating an image of a … Read the rest
